If you are not sure what amplitde, frequency, and/or period is, please
view the Web pages on them.

Set up your graph paper.

Every 6 lines on your graph paper, place a tick
mark for your x-values.

Every 4 lines on your graph paper, place a tick
mark for your y-values.

To check for tick marks that will have a
coordinate point, you must take 6/frequency and it will tell you if you
need more tick marks, if you do then it will tell you the spacing and
it will also tell you which tick marks will get a coordinate point.

Example: If 6/frequency equals 3, then every
third line along the x-axis will have a tick mark and a coordinate
point.

Example: If 6/frequency equals 12, then not
every tick mark will have a coordinate point along the x-axis, every
other tick mark will have a coordinate point (ie. 0, π,
2π)

Start graphing the trigonometric function along
the y-axis.

For the sine function, you will start graphing
at the origin (0,0).

For the cosine function, you will start
graphing at the a value of the
trigonometric function.

Graphing Trigonometric Functions
on the Graphing Calculator(TI-83 or TI-84):

Set your mode to degree

Select mode and make sure degree is highlited. If not,
arrow down to degree and press Enter.

You want to graph in degree mode, even though we graph by
hand usually in radians because radian mode will give you decimals
instead of fractions, but we can then take the degree measure and
convert it to radians by multiplying by π/180°.

Go the the y= screen and type on your equation into y1.

Set up the viewing window.

Zoom, 7 (ztrig)

This window will graph from x = -360° to x =
360°

Once you press Zoom, 7, the graphing calculator will
automatically graph the function.
